In this article we examined 10 key strategies you can use to improve data access performance in EF Core. Additionally, you should fine-tune your database design, indexes, queries, and stored procedures to get maximum benefits. It is imperative that you keep performance in mind from the outset whenever you are building applications that use a lot of data. The default behavior of EF Core is to track objects retrieved from the database. Tracking is required when you want to update an entity with new data, but it is a costly operation when you’re dealing with large data sets.

The EF Core supports relational and non-relational databases, which is possible due to database providers. The Database Provider sits between the EF Core and the database it supports. You should use async code to improve the performance and responsiveness of your application. Below I’ll share a code example that shows how you can execute queries asynchronously in EF Core.

Entity Framework Core 7.0

The code may compile in without any issues but problems can show up in runtime. Common errors happen because the code might not reflect the state of the data source. Or, we might address columns that are removed or changed, or with incorrect column names. The term ORM stands for Object-Relational Mapper, and it automatically creates classes based on database tables, and vice versa is also true. It can also generate the necessary SQL to create the database based on the classes.

Targeting tables are useful when building microservices or .NET applications that are designed to perform a niche task. Entity Framework Core (EF Core) is a ground-up rewrite of Microsoft’s object-database mapping framework. Getting started with EF Core is relatively straightforward, but mastering it can take an entire career. An ORM (Object-Relational Mapper) is used to interact with a database using an object-oriented programming language. ORMs allow developers to work with databases using familiar, object-oriented concepts, rather than writing raw SQL statements. A refresh of version 4.1, named Entity Framework 4.1 Update 1, was released on July 25, 2011.

EF Core Version History

Still, modifications to the naming conventions within EF Core come with significant maintenance costs and the potential to introduce mapping bugs. Developers should embrace EF Core defaults as much as possible to avoid strange edge cases and exceptions. The latter is used to develop applications of any kind, the former what is entity framework makes it easy to build data-oriented applications. However, as we already mentioned, the Model First in Entity Framework Core is not available at the moment. It does not mean it will not be added in the further versions, but if you need the Entity Framework Core model first now, it won’t work, unfortunately.
